POSCO Holdings (PKX) Q4 2025: Lithium Sales Set to Double as Asset Ramp Drives 2026 Inflection
POSCO Holdings enters 2026 with a decisive pivot toward commercial lithium production and overseas steel expansion, after a year marked by operational setbacks and restructuring charges. Portfolio realignment, new resource investments, and the ramp-up of Argentina’s lithium plant position PKX for margin recovery and growth, though steel and battery materials remain exposed to volatile demand and input costs. Investors should watch for the timing and magnitude of lithium profitability, execution on international steel JVs, and the impact of protectionist trade policy on core markets.
Summary
- Lithium Ramp as Margin Lever: Commercial production and sales volumes are set to double, with Argentina’s plant entering full operation.
- Steel Expansion Abroad: Overseas JV negotiations and U.S./India entry strategies move from planning to execution in 2026.
- Portfolio Restructuring Impact: Divestitures and asset exits remove loss-making units, setting the stage for profit improvement.
Business Overview
POSCO Holdings is a diversified industrial group anchored by steel production, battery materials, and resource-based infrastructure. The company generates revenue through domestic and international steel operations, lithium and battery materials (including brine and hard rock extraction), and energy/infrastructure assets such as LNG and palm oil. Major segments include Steel (domestic and overseas), Rechargeable Battery Materials (RBM), Infrastructure (energy, palm oil, construction), and Trading. Steel remains the core, but the group is rapidly expanding its lithium and resource business to capture growth in energy transition supply chains.
Performance Analysis
2025 was a year of contraction and transition for POSCO Holdings. Consolidated revenues fell 5% year over year, with operating profit down 16% amid a confluence of one-off charges and operational headwinds. The fourth quarter was especially weak, driven by major repairs at the Pohang hot-rolled (HR) plant, inventory overhang from pre-tariff imports, and the divestment of the loss-making PZSS plant in China. Ramp-up costs from new lithium and precursor plants further pressured margins, and construction halts at POSCO EMC added to the drag.
Despite these setbacks, management emphasized that core steel operating profit margins improved sequentially through most of the year, and that cost innovation and product mix upgrades helped offset some market softness. Overseas steel units saw mixed results, with profitability gains in Indonesia and Vietnam offset by losses at PZSS (to be excluded from 2026 results). The RBM segment remained loss-making due to lithium price volatility and ramp-up inefficiencies, but is expected to inflect as Argentina’s plant reaches commercial scale. Infrastructure investments, including expanded gas and palm oil assets, are positioned to contribute meaningfully in 2026.
- One-Off Charges Drive Q4 Weakness: Employee compensation from China divestment, POSCO EMC construction stops, and bad debt expenses weighed heavily.
- Steel Margins Up, Volumes Down: Domestic steel margin improvement was offset by a 6% QoQ sales volume drop amid repairs and inventory normalization.
- Lithium Segment Poised for Turnaround: Argentina ramp-up and higher lithium prices set up a profit cycle, though Q1 will still see low-priced legacy orders.
Portfolio restructuring continues, with 28 projects completed and 1.8 trillion won in cumulative cash generated since 2024. The exclusion of loss-making overseas steel assets and the full-year effect of new resource investments are expected to shift group profitability in 2026.
Executive Commentary
"In 2026, we will likely serve up some significant inflection points for POSCO Holdings. First, we have for some time studied various ways to go overseas in steel. This year, we'll see some specific actions... Asset-based lithium operations will begin to generate profits. Our Argentina Lithium Plant 1 will ramp up and begin commercial operation this year."
Kim Sung-Chun, Head of Finance and IR Division (CFO)
"By March end, we will boost utilization rate to more than 60%, and from July to August, we will be in full operation, meaning it will be our first year of commercial production. Recently, lithium prices increased substantially. Argentina plant owns brine assets, so we have a lot of operating leverage in face of lithium price hikes."

Strategic Positioning
1. Lithium Commercialization and Upstream Integration
Argentina’s brine-based lithium plant is moving from ramp-up to commercial production, with sales volumes set to double to 50,000-60,000 tons. POSCO’s investments in both brine (Argentina) and hard rock (Australia) sources, plus the acquisition of new assets, position the group to benefit from rising lithium prices and vertical integration. The company is also investing in direct lithium extraction (DLE), a technology allowing faster and more efficient lithium recovery from brines.
2. Steel Globalization and Product Mix Shift
POSCO is executing on long-planned overseas steel expansion, with JV negotiations in the U.S. and India reaching final stages. Domestically, the focus is on high-margin premium steels and decarbonization technologies (such as EAF and HIREX pilot plants). The company is actively managing product mix to prioritize profitability and resilience to protectionist trade actions.
3. Portfolio Restructuring and Asset Rotation
Ongoing divestitures and restructuring are removing loss-making units and freeing up capital for growth initiatives. The exit of PZSS and other non-core or underperforming assets is expected to reduce group deficits and improve earnings quality in 2026. The group targets 55 additional restructuring projects by 2028, with 1 trillion won in further cash generation.
4. Infrastructure and Resource Investments
New investments in gas (Cenex Energy) and palm oil (Indonesia) will be fully reflected in 2026 results. LNG import agreements and power generation assets are intended to provide stable cash flow and diversify earnings away from cyclical steel and battery materials businesses.
5. Safety and ESG Commitment
After a rise in serious injury cases, POSCO is expanding safety systems, direct CEO oversight, and external audits. Management asserts that safety investment is already industry-leading and will not materially impact profitability, but the group will continue to report transparently on workplace safety metrics.
Key Considerations
2026 is a pivotal year for POSCO Holdings as it transitions from restructuring and ramp-up to growth and margin recovery. Execution risks remain, but the portfolio is more focused and aligned with global energy transition trends.
Key Considerations:
- Lithium Price Sensitivity: Profitability in RBM depends on sustained lithium price recovery and the timing of cost pass-through from spodumene and brine inputs.
- Steel Demand Regionalization: Domestic premiumization and overseas JV execution are critical as global steel demand diverges by region and trade barriers rise.
- Portfolio Simplification: Removal of loss-making assets (e.g., PZSS) and continued restructuring should improve earnings quality and capital efficiency.
- Resource Asset Ramp: New gas and palm oil assets provide margin resilience, but require operational discipline to deliver on profit forecasts.
- CapEx Discipline: Elevated 2026 CapEx reflects upstream and lithium investments, but management signals flexibility to adjust as project negotiations progress.
Risks
POSCO faces persistent risks from steel market cyclicality, global trade protectionism, and lithium price volatility. Cost inflation, input price spread compression (especially for lithium), and execution challenges in overseas JVs could pressure margins. Regulatory shifts, such as the EU CBAM and evolving ESG expectations, add further complexity. While restructuring reduces some downside, the group’s pivot to new growth areas introduces operational and market risks that require close monitoring.
Forward Outlook
For Q1 2026, POSCO guided to:
- Steel sales volume recovery to prior-year levels as repairs conclude and inventory normalizes
- Initial commercial ramp of Argentina lithium plant with utilization above 60% by March, full operation by mid-year
For full-year 2026, management expects:
- Profit improvement from lithium commercialization and portfolio restructuring
- Full-year contribution from new gas and palm oil assets
Management highlighted several factors that will shape 2026:
- “We hope this year will prove to be the inflection point.”
- Ongoing global steel demand divergence and lithium price uncertainty
Takeaways
POSCO Holdings enters 2026 with a more focused, resource-levered portfolio and visible catalysts for margin recovery.
- Lithium Commercialization Is Key: The transition from ramp-up to commercial lithium production, especially in Argentina, will drive earnings inflection if price and volume targets are met.
- Steel Expansion and Restructuring: Execution on overseas JVs and the removal of loss-making assets should lift core profitability and reduce volatility.
- Watch for Margin Spread Volatility: Input cost swings and regional demand shifts in both steel and battery materials remain the primary variables for 2026 performance.
Conclusion
After a year of operational and structural reset, POSCO Holdings is positioned for a pivotal 2026, with lithium and resource asset ramp-up, steel globalization, and portfolio simplification as the main levers. Execution on these fronts will determine whether this year marks the long-awaited inflection in growth and profitability.
Industry Read-Through
POSCO’s 2025 results and 2026 plans highlight the intensifying interplay between traditional steel, battery materials, and resource security in the global supply chain. The group’s pivot to lithium and integrated resource assets mirrors broader industry trends, as steelmakers seek resilience through vertical integration and exposure to energy transition materials. Trade barriers, regional demand divergence, and input cost volatility will remain core themes for global metals and materials players. Competitors with diversified portfolios and upstream integration are likely to outperform, but execution risk and capital allocation discipline will separate winners from laggards in the next cycle.
